Charcoal or wood fires of any sort are prohibited at the park backcountry campsites.

There are no fire restrictions in park campgrounds, day-use picnic areas, and employee residential areas within provided fire rings.

Portable stoves and lanterns which use pressurized liquid, jellied petroleum, or gas fuel and fully enclosed, sheep-herder type stoves with a ¼ inch spark-arrestor screen are permitted park-wide in areas where ground cover and overhead vegetation is cleared within three feet of the device.

Smoking is permitted only inside vehicles, on sidewalks, in gravel or paved parking areas, in developed campgrounds, immediately adjacent to backcountry fire rings, and in designated smoking areas inside buildings. Smoking is prohibited on all trails and thermal areas.

In addition, the following are never permitted in Yellowstone National Park:

Discharge of fireworks or firearms

Use of explosives or pyrotechnic devices

Abandoning or failing to attend a campfire

Driving a vehicle off-road

Smoking in all thermal areas and all posted and designated areas such as trails

These restrictions are designed to protect people, property and the area’s natural resources. Temporary restrictions will remain in place until further notice, and may be increased or reduced at any time due to changes in weather and fire danger.

There have been ten fires in the park this year. Four have been caused by people and six were the result of lightning strikes. Eight fires have been declared out. The Fawn fire was estimated at 915 acres as of 11:30 a.m. Sunday, August 7. Efforts to monitor the fire and complete structure protection at the Fawn Pass backcountry cabin continue. Updates and a fire map are available at: go.nps.gov/yellfawnfire. The Hornady fire, which was reported on Sunday, August 7, is less than one acre and is being suppressed by three NPS firefighters.

A change in the weather forecast for today calls for warmer and drier conditions. Typically, fire activity picks up in the afternoon as temperatures rise, relative humidity levels drop, and gusty winds increase. Fire activity is expected to increase in the coming days. Visitors and surrounding communities should expect varying levels of smoke through the day and smoke levels to increase during the afternoon.

The extended weather forecast calls for continued hot and dry conditions, with a slight chance of isolated afternoon thunderstorms. The potential for fires igniting remains high.
